You are only 5 weeks into flowering and you think you already have a pound?
Heh, not to bring down your spirits but don't get your hopes up until your final product is dryed and cured.
While it may look like alot (it always does), during the drying process (and you better be curing it too!) it loses 75% of it's weight. You heard me right.

And you still never answered me, what kind of light were ya using before the hortilux? Curious minds would like to know!
